Sprinkler



Feb. 11, 1930. w. STEININGER SPRINKLER Filed may 1928 Patented Feb. 11,1 930 UNITED STATES PATENT OFFICE WILLIAM STEININGER, OF BERWYN,ILLINOIS, ASSIGNOR TO W. D. ALLEN MANUFAC- TURING COMPANY, OF CHICAGO,ILLINOIS, A CORPORATION OF ILLINOIS SPRINKLER Application filed May 28,

This invention relates to the art of hose sprinklers, and has referencemore particularly to an improvement in sprinkler heads or nozzles of thetype adapted to deliver the water in the form of either a full stream ora spray. A sprinkler of the type to which my present invention relatesis disclosed in Letters Patent to Henry Gibbs, No. 1,086,288, datedFebruary 3, 191 1, and my present invention is in the nature of animprovement on the sprinkler of the aforesaid patent.

In the device of the said patent there is provided a discharge nozzlehaving a reduced peripherally grooved cylindrical part formed with aneccentric discharge opening, a deflecting plate or fin having its innerend extending along one side of the nozzle, and its outer end benttoward the axis of the nozzle, and a yoke or collar embracing andadjustable around said grooved portion of the nozzle and having flangedends engaging the edges of the deflecting plate and supporting the same.Said yoke or collar forms the means for mounting the deflecting plate onthe nozzle with capacity of adjustment around the latter, whereby a fullstream or a spray may be delivered; and the object of my presentinvention is to improve the mounting means of the deflector plate so asto shorten and simplify the structure, reduce the number of parts, andreduce the cost.

Two slightly differing practical embodiments of the present inventionare illustrated in the accompanying drawing, in which Fig.1 is anelevation;

Fig. 2 is an axial section on line 22 of Fig. 1;

Fig. 3 is an axial section of a modification.

Referring to Figs. 1 and 2, 1O designates a nozzle interiorly threadedfor connection to the threaded end of a hose or pipe 11, with aninterposed packing washer 12, preferably of rubber. On the outer end orface of the nozzle 10 is formed a low circular bearing boss 13 that iscoaxial with the nozzle 10. The

nozzle 10 is further formed with an eccentric discharge openingl4cextending through a nipple 15, which latter is encircle by the boss13. 16 designates the deflector or fin, consisting of an approximatelyflat piece of 1928. Serial No. 281,208.

metal formed near its inner end with an integral laterally offset shankportion 17 and a centrally apertured base plate 18 that has a bearingfit on the boss 13 and-lies in contact with the face of the nozzle 10.After the base plate of the deflector has been mounted on the .boss 13,the marginal portion of the latter is swaged over the inner periphery ofthe base plate 18 forming a lip or flange 19 that securely confines thebase plate on the outer end of the nozzle. The lip 19 clamps the baseplate 18 of the deflector With sufficient friction to permit thedeflector and its base plate to be bodily shifted around the boss and tohold the deflector in adjusted position. It will be observed that thedeflector 16 is inwardly inclined toward the axis of the nozzle, sothat, with the parts positioned as shown in Fig. 2, the jet of waterissuing from the nipple 15 strikes the inner face of the deflector 16and is sprayed thereby, Then, however, the deflector 16 is shifted 180from the position shown in Fig. 2, the jet will pass the deflector inthe form of a solid stream.

By shifting the deflector to intermediate positions, the jet ispartially sprayed.

In the embodiment shown in Fig. 3, the nozzle is formed in two parts, anouter shell portion 10' and a central body portion formed as a plug 10that is driven tightly into the shell portion 10. The plug 1O is formedwith the nipple 15 and eccentric discharge opening 14 extendingtherethrough, with the low bearing boss 13, and with a preformed annularlip or flange 19. In assembling these parts, the apertured base 18 ofthe deflector is laid on the outer face of the shell portion 10 of thenozzle, and the body portion or plug 10"- is then driven through thebase portion 18 and into the she-ll portion 10, the lip or flange 19having a friction bearing on the base 18. This construction, as comparedwith that shown in Fig. 2, has the disadvantage of a greater number ofparts, but it has the advantage of a preformed retaining lip or flangewhich does not require to be swaged down into place.

By comparison of the above structures with that disclosed in the Gibbspatent hereinabove referred to, it will be seen that the newconstruction herein disclosed considerably shortens the total length ofthe nozzle and deflector plate, reduces the number of parts by formingthe deflector plate and its shank and base all in one piece, and thusconsiderably reduces the cost of manufacture.

I claim 1. A sprinkler of the type described, comprising a dischargenozzle formed with an eccentric discharge nipple and provided on itsouter end with a low boss coaxial with said nozzle and surrounding saidnipple, a deflectorhaving a laterally extended flat apertured base plateseated on the outer end of said nozzle and frictionally fitted on and adjustable around said boss whereby to shift said deflector into and outof alignment with the nipple discharge orifice, and means for confiningsaid base plate on said boss.

2. A sprinkler of the type described, comprising a discharge nozzleformed with an eccentric discharge nipple and provided on its outer endwith a low circular bearing boss coaxial with said nozzle andsurrounding said nipple, a deflector blade having a laterally extendedflat apertured base plate seated on the outer end of said nozzle andfrictionally mounted on and adjustable around said boss, and an annularlip on the outer end of said boss overlapping and confining said baseplate on said boss and permitting said base plate to be adjusted aroundsaid boss whereby to shift said deflector into and out of alignment withthe nipple discharge orifice.

WVILLIAM STEININGER.
